HSE MIEM Professor Elected Fellow of American Physical Society

HSE MIEM Professor Elected Fellow of American Physical Society

The American Physical Society (APS) has recognised HSE MIEM Professor Lev Shchur for his innovative use of computer simulations and the development of superior random number generators for their use in statistical physics. Professor Shchur is the only academic working in Russia to be selected as APS Fellow in 2017.

Founded in 1899 by physicists from Columbia University, the American Physical Society is one of the oldest academic communities in the world. The society includes 14 divisions and nine thematic groups representing all key areas of modern-day physics.

Lev Shchur’s academic interests lie at the interface of theoretical physics and computer software. He is a leading researcher with the Landau Institute for Theoretical Physics in Chernogolovka, Russia. At MIEM, Professor Shchur heads the Joint Department with RAS Dorodnicyn Computing Centre and teaches courses on distributed computing and parallel programming.

Professor Shchur is also the author of more than 140 works that have each made a significant contribution to contemporary science:

  • The angle of transversal homoclinic intersection in Yang-Mills equations was numerically determined, which though the help of the computer has proven the non-integrability of Yang-Mills fields.
  • In a work co-authored with S. Manakov, stochasticity was found in the scattering of vortex pairs, which is evidence of the non-integrability of two-dimensional hydrodynamic equations.
  • A paper co-authored with A. Talapov showed how specialised computers were built to research spin models. A correlation function was numerically obtained for the first time ever, and it was shown that impurities do not change the universality class. Instead they simply modify the correlation length with logarithmic corrections.
  • Together with P. Bueter and B. Barash, numerical assessments were created on universal combinations of critical amplitudes in the two-dimensional Potts model, while the precise reduction of logarithmic corrections was shown analytically in the universal relations of critical amplitudes.
  • A work co-authored with H. Blöte explained the undesirable correlation between the cluster Monte Carlo method and a random number generator on shift registers. A theory was developed on such correlations.
  • A new approach was proposed towards the development of pseudo-random number generators based on the mapping torus and hidden variables. Together with L. Barash, a library of effective random number generators was developed.
  • In a work co-authored with M. Novotny, a classification system was proposed for parallel discrete event simulation (PDES) algorithms using the analogy of the evolution of the PDES time horizon together with the evolution of the surface profile in Kardar–Parisi–Zhang equations.

Russian Scientists Discover Method for Enhancing the Capacitance of Supercapacitors

A supercapacitor is a device capable of rapidly storing and releasing a significant amount of energy within a matter of seconds. It consists of metal electrodes immersed in an electrolyte solution. In their model, MIEM HSE scientists substituted the conventional low-molecular-weight electrolyte with a polyelectrolyte, resulting in an unexpected and adverse physical phenomenon: supercapacitors experience a reduction in capacitance when the pore size of the electrode is below 1 nm. By carefully selecting optimal conditions for polyelectrolytes, it becomes possible to develop supercapacitors that are not only more robust but also more efficient in their performance. The study has been published in Physical Review E.

Physicist from HSE University-St Petersburg Ranked Russia’s Number One Scientist in Electronics and Electrical Engineering by Research.com

The academic platform Research.com has published a ranking of the best scientists in the field of electronics and electrical engineering in 2022. In Russia, first place in Electronics and Electrical Engineering went to Alexey Zhukov, Academic Supervisor of the International Laboratory of Quantum Optoelectronics, Doctor of Physical and Mathematical Sciences, Corresponding Member of the Russian Academy of Sciences.

Using Simple Salts to Produce Safer Electrolytes for Aqueous Batteries

A team of Russian scientists including HSE MIEM researchers have used superconcentrated salt solutions to produce effective water-based electrolytes that demonstrate high conductivity and electrochemical stability and require lower amounts of non-toxic salts, making the batteries safer and less expensive than classical non-aqueous ones. The study is published in The Journal of Physical Chemistry C.

Russian physicists have demonstrated how tunnelling contacts can be used for single-particle states spectroscopy in carbon nanotubes. The proposed technology of tunnelling contact fabrication and the spectroscopic method will help measure the exact nanotube bandgap value, which is the key characteristic required for design of any nanotubes-based electronic devices. Applied Physics Letters publishes the result of the study.

Researchers Compare Energy Consumption During Extraction and Synthesis of One Diamond Carat

Researchers from HSE University, RAS, and Skoltech have compared actual specific energy consumption in the production of diamonds using traditional (mining) and innovative (synthesis) methods. Depending on the technology, 36 to 215 kWh of energy is consumed to produce a 1 carat diamond. It turned out that not all diamond synthesis technologies surpass extraction methods in terms of energy efficiency. The results of the study were published in the journal Energies.

Researchers Begin to Understand Correlation of Schumann Resonances and Dust Storms on Mars

The interaction of dust particles in Martian dust storms may cause electric fields that are powerful enough to have charges that induce standing electromagnetic waves known as Sсhumann resonances. This is the conclusion drawn by physicists from HSE University, the Space Research Institute, and MIPT. The paper was published in Icarus journal.

Statistical Physics Can Help Uncover the Impact of Media on Decision Making

Students and researchers from HSE University and the Landau Institute for Theoretical Physics have examined the widely known ‘Prisoner’s Dilemma’ game using methods from statistical physics. They used the mean-field concept, a common tool for studying the physics of many-particle systems, to describe human decision-making processes. Researchers suggest that this model may be helpful for understanding systems with many participants. The results of the study are published in the September issue of the Physics Review Research journal.

As part of the Belle experiment, researchers were able to measure the energy dependence of e+e- -> B-anti-B, B-anti-B* and B*-anti-B* reactions in the 10.63 GeV to 11.02 GeV energy range for the first time. The new data will help clarify the nature of the group of exotic Upsilon mesons that have mass in this range. The results of the study were published in the Journal of High Energy Physics.

Russian Researchers Obtain New Data on Solar Magnetic Field Asymmetry

Researchers from the Institute of Earthquake Prediction Theory and Mathematical Geophysics (Russian Academy of Science) and HSE University have proven that asymmetry between meridional flows in the northern and southern hemispheres of the Sun depends on the anomalies of the solar magnetic field. Research undertaken by Elena Blanter and Mikhail Snirman reveals new aspects of the importance of solar magnetic field asymmetry for predicting the anomalies of the Sun’s activity. The article has been published in Solar Physics.
